Well I love what Carrey did with the Riddler. But it wasn't true to the character it was a Gorshin rip-off. The Riddler Nolan would do would be more true to the comic roots, as cold, calculating, and manipulative. Such as the TAS version of the Riddler.

I already like the fact that we have the Scarecrow and Ra's, two characters never done. Now we have a new interpretation of the Joker, and what seems to be Two-face done right this time.

But of course he can pull out anyone, but I don't think we will see the likes of Mr. Freeze, Bane, Clay Face or Man-Bat. Nolan's films seem to grounded more in reality than the previous ones, my bet is will we see either: The Penguin (done more true to the character of the comics), Catwoman, Poison Ivy, or the Riddler in Batman 3.

I agree, he wasn't completely true to the character, Carrey's Riddler still reminds me of the Joker in a lot of ways but I still enjoyed the performance.

I'm really happy that we got Ra's Al Ghul. Besides Bane, the Joker, & Two-Face, he's one my favorite Batman villains as is the Scarecrow who I'm glad we'll be getting in TDK as well.

I think that Bane is somewhat realistic, it's not like he's a character like Clayface that could never ever happen. Bane is one of those characters I could see happening in real life if there were actually a way to pump steroids from your arms into your head & then get bigger in muscle size & in height, etc. If we don't get Bane, I want to either see the Riddler or Catwoman, please no Poison Ivy. A woman who is obsessed with plants isn't interesting to me but I did like TAS incarnation.
